The Fire is an intense punishment, in which there are different types of torment, to escape which people would give the dearest possessions that they own:
“As for those who reject Faith, and die rejecting – never would be accepted from any such as much gold as the earth contains, though they should offer it for ransom. For such is [in store] a penalty grievous and they will find no helpers”. (3:91)
“As to those who reject faith – if they had everything on earth and twice repeated, to give as ransom for the Penalty of the Day of Judgement, it would never be accepted of them. Theirs would be a grievous Penalty.” (5:36)
Muslim reports from Anas ibn Maalik that the Messenger of Allah (saw) said: “One of the people of Hell who found the most pleasure in the life of this world will be brought forth on the Day of Resurrection, and will be dipped into the Fire of Hell. Then he will be asked: O son of Aadam, have you ever seen anything good? Have you ever enjoyed any pleasure?” He will say, “No, by Allah (swt), O Rabb”” (Muslim, Mishkaat al-Masaabeeh, 3/102).
Just a few short moments will make the kuffaar forget all the good times and pleasure that they had enjoyed. al-Bukhaari and Muslim report from Anas ibn Maalik that the Messenger of Allah (saw) said, “On the Day of Resurrection, Allah will say to one whose punishment in the Fire is the lightest, “If you had whatever you wanted on earth, would you give it up to save yourself?” He will say, “Yes”. Allah (swt) will say, “I wanted less than that from you: when you were still in the loins of Aadam, I asked you not to associate anything in worship with Me, but you insisted on associating others in worship with Me””. (al-Bukhaari, in Kitaab ar-Raqaaq, Baab Sifaat al-Jannah wan-Naar, Fath al-Baari, 11/416, See also Mishkaat al-Masaabeeh, 3/102)
The horror and intensity of the Fire will make a man lose his mind, and he would give up everything he holds dear to escape it, but he will never be able to:
“..the sinner’s desire will be: would that he could redeem himself from the Penalty of that Day by [sacrificing] his children, his wife and his brother, his kindred who sheltered him, and all, all that is on earth, so that it could deliver him. By no means! For it would be the Fire of Hell! Plucking out [his being] right to the skull”. (70:11-16)
This horrendous ongoing punishment will make the life of these evildoers one of continual sorrow and pain.
